DETAILED DESCRIPTION

A technical solution of the present disclosure will be clearly and completely described hereinafter in conjunction with drawings of the present disclosure. It is apparent that the described embodiments are a part, rather than all, of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments acquired by those of ordinary skills in the art without creative work are within the scope of the present disclosure.

The information transmission method, the base station, the mobile terminal, and the computer readable storage medium provided by the present disclosure may solve a problem that in a case that multiple mobile terminals perform an access through a RACH resource configured at one fixed frequency point, a congestion probability of random access is improved.

As shown in FIG. 1, the present disclosure provides an information transmission method. The information transmission method is applied to a base station and includes a step 101.

Step 101: transmitting to a mobile terminal configuration information of a target frequency point used by the mobile terminal in a random access procedure, wherein the configuration information includes time slot information corresponding to the target frequency point and/or identification information of the target frequency point.

The target frequency point includes a first service frequency point of a non-New Radio (NR) communication system and/or a second service frequency point of a NR communication system, wherein the NR communication system is a communication system in which the mobile terminal is located, the non-NR communication system is specifically a Long Term Evolution (LTE) communication system, and the first service frequency point is specifically 1.8 GHz or 800 MHz, or 900 MHz, or 2.3 GHz, or 2.6 GHz, or 2.1 GHz. The 1.8 GHz is taken as an example below, and other frequency points are similar in principle. The second service frequency point is a frequency point deployed for a 5G NR including 3.5 GHz or other frequency points. The 3.5 GHz is taken as an example, and the other frequency points are similar in principle. The target frequency point may be a frequency point used by a first interactive message msg. 1 (a preamble sequence), a second interactive message msg. 2, a third interactive message msg. 3, a fourth interactive message msg. 4 and a fifth interactive message msg. 5 in a random access procedure, or may be a frequency point used in an entirety of a random access procedure.

The frequency points mentioned above are commonly used in the industry, and specific information of the frequency point is as follows:

For a time division duplex (TDD) system:

1.8 GHz: 1880-1900 MHz (bands: 39);

2.3 GHz: 2320-2370 MHz, or 2300-2320 MHz, or 2370-2390 MHz (bands: 40);

2.5 GHz: 2575-2635 MHz, or 2555-2575 MHz, or 2635-2655 MHz (bands: 41).

For a Frequency Division Duplex (FDD) system

1.8 GHz: 1755-1785 MHz/1850-1880 MHz;

2.1 GHz: 1955-1980 MHz/2145-2170 MHz;

The frequency points of 800 MHz, 900 MHz also include any one of 800 MHz and 900 MHz used in a Code Division Multiple Access (CDMA) system, a Global System for Mobile Communications (GSM) system, a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system.

The time slot information includes a time slot or a part of time slots configured by a base station other than a predetermined time slot, wherein the predetermined time slot is a time slot for downlink reception by the mobile terminal using a downlink service frequency point of the NR communication system.

Specifically, the predetermined time slot includes a time slot for downlink reception using a downlink service frequency point in a connected state and a time slot for downlink reception using a downlink service frequency point in an idle state. The time slot for downlink reception using a downlink service frequency point in the connected state includes a time slot for receiving downlink control information, a time slot for receiving downlink data, a time slot for receiving a broadcast message, a time slot for receiving a paging message, and a time slot for receiving reference information; the time slot for downlink reception using a downlink service frequency point in the idle state includes a time slot for receiving downlink control information, a time slot for receiving a paging message, and a time slot for receiving reference information.

For example, the NR system shares 1.8 GHz with the LTE system in uplink, and in a case that downlink reception is performed using 3.5 GHz, uplink transmission may not be performed using 1.8 GHz at the same time; only in a case that the downlink reception is not performed using 3.5 GHz, the mobile terminal (UE) may perform uplink transmission using 1.8 GHz. This scheme allows the UE to have only one transceiver for performing uplink and downlink transmission at separated time points. In this way, not only a cost of a duplexer may be saved, but also influence from crosstalk interference and second harmonics may be reduced.

Here, in a case that the 5G NR (new radio) is deployed on a C carrier (around 3.5 GHz), an uplink coverage is enhanced by sharing a low frequency point with the LTE system, and an access success rate of a mobile terminal at a cell edge is improved.

As an optional implementation, before the above step 101, the information transmission method further includes acquiring, by pre-definition, configuration information of the target frequency point used in the random access procedure.

The step 101 specifically includes transmitting the configuration information of the target frequency point to a mobile terminal through at least one of a dedicated Radio Resource Control (RRC) signaling, a RRC reconfiguration message, a RRC configuration message, a Random Access Channel (RACH) configuration signaling, a system message, and a broadcast message.

Optionally, before the step 101, the method further includes acquiring capability information reported by the mobile terminal, wherein the capability information includes a frequency point supported by the mobile terminal; configuring the target frequency point used by the mobile terminal in the random access procedure based on the capability information.

Specifically, if the frequency point supported by the mobile terminal includes a first service frequency point, it may be determined that the target frequency point is a first service frequency point and/or a second service frequency point; if the frequency point supported by the mobile terminal includes the second service frequency point, it may be determined that the target frequency point is the second service frequency point.

Further, as shown in FIG. 2, after the above step 101, the information transmission method further includes a step 102.

Step 102: performing a random access based on the configuration information.

The configuration information is used for transmitting an interactive message in a random access procedure, wherein the interactive message includes at least one of the preamble sequence, the second interactive message, the third interactive message, the fourth interactive message, and the fifth interactive message.

Further, as shown in FIG. 2, after the step 102 of performing the random access based on the configuration information, the information transmission method further includes a step 103.

Step 103: receiving uplink transmission data transmitted by the mobile terminal based on the configuration information.

The above step 102 includes sub-steps 1021-1022.

Sub-step 1021: receiving the preamble sequence transmitted by the mobile terminal; and

Sub-step 1022: transmitting the second interactive message to the mobile terminal.

In addition, before the sub-step 1021 of receiving the preamble sequence transmitted by the mobile terminal, the above-mentioned step 102 further includes a sub-step 1020.

Sub-step 1020: transmitting correspondence relationship between a grouping identifier of preamble sequences and a configured frequency point to the mobile terminal, so that the mobile terminal selects the preamble sequence based on the correspondence relationship and transmits the preamble sequence.

Here, the base station transmits the correspondence relationship between the grouping identifier of the preamble sequences and the configured frequency point to the mobile terminal, so that the mobile terminal selects the preamble sequence based on the correspondence relationship, a frequency point supported by the mobile terminal and frequency point coverage information of a cell. Assuming that an uplink frequency point supported by the mobile terminal includes the first service frequency point and the second service frequency point, and a location where the mobile terminal is located is covered by only the first service frequency point, preamble sequences are grouped into two groups A and B, a frequency point corresponding to the group A is the first service frequency point, and a frequency point corresponding to the group B is the second service frequency point, then a preamble sequence in the group A is selected and transmitted to the base station.

Further, the step 1021 includes: based on the correspondence relationship between the grouping identifier of the preamble sequences and the configured frequency point and the received preamble sequence transmitted by the mobile terminal, acquiring configuration information of a first target frequency point used for a first subsequent interactive message and/or uplink data transmission, wherein the first subsequent interactive message includes at least one of the third interactive message, the fourth interactive message, and the fifth interactive message.

In this case, the step 1022 includes transmitting the second interactive message in the random access procedure to the mobile terminal, the configuration information of the first target frequency point is carried in the second interactive message or in a Random Access Radio Network Temporary Identifier (RA-RNTI) used by the second interactive message.

The RA-RNTI herein is calculated by a predetermined RA-RNTI calculation formula. The RA-RNTI calculation formula in the LTE system is: RA-RNTI=1+t_id+10*f_id; where t_id is a time resource of a Physical Random Access Channel (PRACH) resource, that is, a number index of a first subframe. f_id is a frequency resource of the PRACH resource, that is, a frequency-domain number within the subframe.

The RA-RNTI calculation formula in a cellular-based Narrowband Internet of Things (NB-IoT) is:

RA-RNTI=1+t_id+10*f_id+60*(SFN_id mod (Wmax/10)), where t_id is the time resource of the PRACH resource, that is, the number index of the first subframe. f_id is a frequency resource of the PRACH resource, that is, the frequency-domain number within the subframe, SFN_id is a first radio frame number of the PRACH resource, Wmax is a maximum Random Access Response (RAR) window length (the number of subframes), a value of which is 400 in the NB-IoT.

Based on the above formula, an optional implementation of carrying the configuration information in the RA-RNTI is:

RA-RNTI=1+t_id+10*f_id+N*carrier_ID,

or RA-RNTI=1+N*carrier_ID+N1*t_id+N2*f_id,

or RA-RNTI=1+t_id+N*carrier_ID+N1*f_id.

Where, t_id is the time resource of the PRACH resource, that is, the number index of the first subframe, f_id is the frequency resource of the PRACH resource, that is, the frequency-domain number within the subframe, carrier_ID refers to a corresponding frequency point number (an identifier) in the present disclosure, and parameters N, N1, N2 need to be determined based on the number of time-frequency resources and the number of available frequency points.

In addition, in the 5G NR, the RA-RNTI calculation formula may also carry information of a Synchronization Signal block (a SS block) or a Beam ID. If a beam-related ID is added, then the above formula may also be added with an item corresponding to the beam_ID.

Further, after the sub-step 1022, the step 102 further includes sub-steps 1023-1024.

Sub-step 1023: receiving the third interactive message transmitted by the mobile terminal.

Sub-step 1024: transmitting the fourth interactive message to the mobile terminal.

The sub-step 1023 includes acquiring configuration information of a second target frequency point carried in the third interactive message and used for a second subsequent interactive message and/or uplink data transmission, wherein the second subsequent interactive message includes at least one of the fourth interactive message and the fifth interactive message.

In this case, the sub-step 1024 includes configuring, based on the configuration information of the second target frequency point carried in the third interactive message, configuration information of a third target frequency point used for subsequent uplink data transmission, and transmitting the configuration information of the third target frequency point used for subsequent uplink data transmission to the mobile terminal through the fourth interactive message.

Here, the configuration information of the third target frequency point may be the same as the configuration information of the second target frequency point, or may be different from the configuration information of the second target frequency point.

The information transmission method of the present disclosure transmits to a mobile terminal configuration information of a target frequency point used by the mobile terminal in a random access procedure, wherein the configuration information includes time slot information corresponding to the target frequency point and/or identification information of the target frequency point. The configuration information of the present disclosure carries the time slot information corresponding to the target frequency point and/or the identification information of the target frequency point, so that the mobile terminal may accomplish uplink access at different frequency points in a case that the mobile terminal performs a random access, thereby effectively reducing a probability of access failure or a congestion probability of random access.

As shown in FIG. 3, the present disclosure also provides an information transmission method. The information transmission method is applied to a mobile terminal and includes a step 301.

Step 301: acquiring configuration information of a target frequency point used in a random access procedure, wherein the configuration information includes time slot information corresponding to the target frequency point and/or identification information of the target frequency point.

Here, the configuration information of the target frequency point used in the random access procedure is acquired to facilitate the mobile terminal to perform random access and/or uplink data transmission based on the configuration information.

As an optional implementation, the configuration information of the target frequency point used in the random access procedure is acquired through pre-definition.

Specifically, the step 301 includes acquiring the configuration information of the target frequency point through receiving at least one of a dedicated Radio Resource Control (RRC) signaling, a RRC reconfiguration message, a RRC configuration message, a Random Access Channel (RACH) configuration signaling, a system message, and a broadcast message transmitted by a base station.

The time slot information includes a time slot or a part of time slots configured by a base station other than a predetermined time slot, wherein the predetermined time slot is a time slot for downlink reception by the mobile terminal using a downlink service frequency point of the NR communication system.

The target frequency point includes a first service frequency point of a non-New Radio (NR) communication system and/or a second service frequency point of a NR communication system, wherein a communication system in which the mobile terminal is located is the NR communication system.

Here, the time slot information includes a time slot or a part of time slots configured by a base station other than a predetermined time slot, wherein the predetermined time slot is a time slot for downlink reception by the mobile terminal using a downlink service frequency point of the NR communication system.

The time slot for downlink reception using a downlink service frequency point in the connected state includes a time slot for receiving downlink control information, a time slot for receiving downlink data, a time slot for receiving a broadcast message, a time slot for receiving a paging message, and a time slot for receiving reference information; the time slot for downlink reception using a downlink service frequency point in the idle state includes a time slot for receiving downlink control information, a time slot for receiving a paging message, and a time slot for receiving reference information.

Further, after the above step 301, the information transmission method further includes a step 302.

Specifically, the acquired configuration information is used for transmitting an interactive message in a random access procedure, wherein the interactive message includes at least one of a preamble sequence, a second interactive message, a third interactive message, a fourth interactive message, and a fifth interactive message.

Further, after the above step 302, the information transmission method further includes a step 303.

Step 303: transmitting uplink data based on the acquired configuration information.

Further, the above step 302 includes sub-steps 3021-3022.

Sub-step 3021: transmitting the preamble sequence to the base station through the acquired configuration information.

Sub-step 3022: receiving the second interactive message transmitted by the base station in the random access procedure.

Optionally, before the sub-step 3021, the step 302 further includes receiving correspondence relationship between a grouping identifier of preamble sequences and a configured frequency point transmitted by the base station, and selecting, based on the correspondence relationship, the preamble sequence to be transmitted to the base station.

Optionally, the above step 302 includes: in a case that the second interactive message transmitted by the base station or a Random Access Radio Network Temporary Identifier (RA-RNTI) used in the second interactive message carries the configuration message of the first target frequency point for a first subsequent interactive message and/or the uplink data transmission, transmitting the third interactive message based on the configuration information of the first target frequency point; otherwise transmitting the third interactive message based on the acquired configuration information; wherein the first subsequent interactive message includes at least one of the third interactive message, the fourth interactive message, and the fifth interactive message.

In the present disclosure, a frequency point different from that used in the random access may be configured for subsequent data transmission, and a crosstalk interference or an interference from a second harmonic to which the UE is subjected may also be effectively reduced.

A specific application flow of the present disclosure will be described below.

1. A mobile terminal transmits a first interactive message in a random access procedure (RACH) using a preset frequency point or a frequency point configured by a base station.

The first interactive message is a message 1 (msg. 1), and the frequency point configured by the base station is transmitted to the mobile terminal through a system message (SI) or a dedicated RRC signaling, and the first interactive message is a preamble sequence (preamble).

It should be noted that the interactive messages of the present disclosure refer to interactive messages in the random access procedure.

Optionally, frequency point information is distinguished through grouping preamble sequences, and a preamble sequence selected by the mobile terminal is transmitted to the base station. The base station may select, for the UE based on the group in which the preamble sequence transmitted by the UE is located and the correspondence relationship between a grouping identifier of a preamble sequence and a configured frequency point, resources such as a frequency point resource, a time-frequency domain resource, or a codeword resource used for at least one of the subsequent second interactive message msg. 2 and the third interactive message msg. 3, the fourth interactive message msg. 4, the fifth interactive message msg.5 and a data transmission message.

In addition, only the above two steps need to be performed in case of a non-contention-based random access; following two steps are also included in case of a contention-based random access.

3. The UE transmits the msg. 3 at a preset or configured frequency point.
